New Alfa awus036ach help

Hi all
Just bought the new Alfa awus036ach and been trying to enable it all day. My built in wireless card show up when enter ifconfig or any command but the USB adapter does not only under lsusb can I find it. lsusb list the chip set and info. So my question is how to enable the USB adapter? I'm running Kali Linux 4.0 Sana amd-64 fully updated. on my laptop dual boot with window (not a VM its DUAL BOOT). The adapter works great on windows but windows sucks I want it for Kali please help me. I'll be back in the morning. Thanks in advance!

used the following commands it works now BUT both network cards turn on the alfa and my bulit in athros when i turn off the pci card the usb goes off too. also i try to put the alfa into mode monitor and system says
root@hd:~# ifconfig wlan1 down
root@hd:~# iwconfig wlan1 mode monitor
Error for wireless request "Set Mode" (8B06) :
SET failed on device wlan1 ; Invalid argument.

yeah i did that tried ifconfig wlan1 down iwconfig wlan1 mode monitor ifconfig wlan1 up<---all errors then tried airmon-ng which works airodump-ng goes into monitor but doesn't show any connections at all and seems to only scan 2.4g. i dont know just wiped my whole drive reinstalled windows 8 ill wait a few months until other ppl buy the new adapter and figure it out.btw the adapter works great on windows.. lol i was getting no connections with my built in card now get 6 with three bars there all 2.4g from about 2 blocks or more away know one seems to have 5g here.

I have the same issue..does somebody has found the correct "patched" drivers?

I have bought this as replacement for my old AWUS036H card. It looks like it is not supported anymore by Kali developers and is end of life.
It should be nice if the Kali developers can implement the drivers into Kali, just like they did with the drivers for AWUS036H.

i couldn't get the card into monitor mode using vverloop's post. The card thats featured in the kali blog iis useless without the ability to use monitor mode and injection. Anyone else have it working somehow?

I got the driver working with injection on an older Kali distro. But guess what, the new Kali release, comes til Linux 4.9.0 kali4 headers, and the installation of the driver asks for kali3 headers so it doesn't install properly.

I think the driver must be updated, or I need to understand something. Cause, it doesn't work.

Anyways, Soledge, don't use a VM because then it won't work.
If that doesn't work and you see an installation error message, then try an earlier Kali release.

The device works in virtual machine if you enable USB 3.0 support-
If you have problems with the dkms package you can always install the source.
The drivers used to build the dkms package are taken from there: https://github.com/astsam/rtl8812au
I just updated Kali Linux.

Thank you for providing this info. Im having troubles using the adapter to find APs. all of my other adapters find quite a few more than the one my ACH found.
I tested it on my Alfa NH, NHA and WN722N. all cards found at least six access points but the ACH. what gives?
I also adjusted the txpower to see if that would have any effect but it didnt seem to help

Be sure to clean any previous installation before installing the drivers you want to try.
You really have to use airmon-ng check kill or kill any process such as wpa_suppplicant, network-manager before using monitor mode.
I see what you mean, i don't know the exact reason, it can happens, i think when you start the PC with the USB plug-in. I am not really sure, i have been trying many drivers for more than one year in different distributions,
Anyway in latest kali, that what happened to me with airodump-ng
Very bad! I should have a full shell of PA in less than 10 seconds. and i do not even have 15
So
1) I brought the interface down again ifconfig wlan1 down
2) Unpluged the USB device
3) Plug it again
4) enable mode monitor iwconfig wlan1 mode monitor
5) bring the interface up ifconfig wlan1 up
Now it works as it should:
I did not even scanned for 4 seconds and my shell was full.
The day and the night... Don't ask me why. Network manager and System.d are bitches.

I tried installing the drivers for the awus036ach as well and am having issues, it works great on my windows10 though. My problem seems basic but I can not get it to install drivers properly. The system can see it as Bus 001 Device 004: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter. This is usb kali with persistence.
I get the following errors I have tried the instruction to install drivers for this on the kali website blog page talking about this adaptor. (apt-get update and then apt install realtek-rtl88xxau-dkms)
Just wondering if someone can point me in the right direction!

It looks like "kernel headers for this kernel does not seem to be installed." You should install kernel headers.

apt-get install -y linux-headers-$(uname -r)

Yes I tried that with this result. I might have messed up something along the way in my desperation to get something to work lol. I am not sure why it looks for those old packages, does not seem right to me. Why it trys the 4.6 I have NO idea heh, i fully updated and sources list is good....I hate to have to redo my persistence stick all over again with a new weekly image or at least the latest image because of something that seems simple...I can not tell where it tells it to look for 4.6 when it should be 4.9 I assume. Even manually installed latest linux-header and linux-image...just trys looking for 4.6 and uname shows 4.6 heh, my persistence stick must be the issue, I think its time forma redo

Guys!
I have been trying with the drivers from the new branch from astsam .
And everything is going more smoothly both in managed and monitor mode.
The drivers are not the one in the dkms package, you have to install them from Git Hub repository.

If you don't know how to use git hub, steps would be:
1) install git

Code:

sudo apt install git

2) download branch 5.1.5 from astsam repository

Code:

git clone -b v5.1.5 https://github.com/astsam/rtl8812au.git

3) locate your shell in the branch

Code:

cd rtl8812au

4) Complie

Code:

make

5) install

Code:

sudo make install

Before doing that make sure:
1) if you installed previously a driver from git hub, you have to erase any previous module 8112au.ko
It is located in an actualized system in

.
2) If you installed the driver with the dkms package provided by Offensive security simply use aptitude to remove it and maybe restart your computer to avoid any troubles installing version 5.1.5

Code:

sudo apt autoremove realtek-rtl88xxau-dkms && sudo systemctl reboot

You will see that with this new drivers airdoump-ng windows populate much more quickly; really at full speed.
Try them, They really worth it!
Do feedback: if they work better for you too i will reopen the bugtrack ticket to ask for upgrading the dkms package from 4.3.21 to 5.1.5

kcdtv, I tried your instructions and get this error, at this step. I did an uninstall of previous driver as instructed. It worked with kali's drivers before but slow like you mentioned.

I am using the latest weekly image on my persistence stick, unfortunately I updated/upgraded kali before trying your guide which seems in my case to make some driver installs get errors, and the kernel header problems pop up etc.

Okay, so i followed kcdtv's post to get the version 5 branch drivers installed. When I run airmon-ng it shows ??????? as my driver now. did i miss something? I'm getting the impression that something didn't install properly. the adapter has also been acting finicky. It wont turn back on if unplugged and plugged back in, and it no longercomes up with ANY Access Points in airodump-ng.

I hope somebody can help.

Update::
Flashing my system with kali image and installing drivers worked!
I had to do an os update to get headers to install.

yes you were right about that, updating the headers worked this time with the brand new kali install, thx.
now I just need the adapter to work, it will see it in lsusb, I must have missed something somewhere, I will keep trying!

EDIT - Kept trying, reinstalled persistence again lol, but did not install the kali drivers first from the new blog how to this time...instead installed yours right off the bat and voila! Thanks!

Hi guys!
@ undersc0re
I think that it would have been enough just to "apt autoremove dkms" too after removing the module rtl81xxau in order to totally get rid off anything linked to the old drivers.
Glad to know that you got there!
Did you noticed too that the USB is working much more "fluently" with this drivers?
@ Soledge
If you installed the dkms package previously, try to remove dkms itself and restart your system.

I did a kali 2017.1 flash on my pc and now things are working much better with the version 5 drivers. its still not perfect but its a lot better than before.
I hope the developer continues to work on getting things like txpower adjusting fixed. right now i think its the best driver so far.

Yes working much better! Just have to start it to monitor mode manually for things but no big deal! Thanks for the tips.

what is everyone getting for tx power in monitor mode using the new branch astsam drivers installed? I get 12 db as installed with no modifications after.
is it lower tx while testing so the usb is not overloaded?

method worked for me i am using the netgear a6100 but of course they possess the 8812au chipset, i cant set monitor mode with airmon-ng i have to set it manually in terminal, but it is working again tx mode is only 12 setting freq to 5G works as well. injection doesnt seem too good and kind of takes longer to connect back to wifi than 4.3.21 after setting mode back to managed and service network-manager start but overall it does work.

Hello there!
This issue is driving me crazy for a week now... hope you have a solution for me!
I am trying to install drivers for my brand new Alfa AWUS036ACH but I am running out of ideas here, I cant manage to make the "make" tool to work nor my dkms install.
Here is what I did so far:

I tried your methods in order to set my own adapter the firs one from github didn't work as well but your 2nd method worked well when i use uname -r i get: 4.9.0-kali4-amd64 and not 3 like yours
i don't know if that's the issue but it worth trying

Second method (dkms way) should be the good one now that kali 2017.1 allows it.
Sadly for me, my uname output keeps being 4.9.0-kali3-amd64. I still have no idea how to switch to the new kernel (kali4) at this point, or how to manage to finally light the little blue light inside the wireless card.

I see, you are replying to everyone with passion. Thank you for that help.
Alfa awus036ach was also not getting installed on Kali (dual boot). Your last suggestion about apt dist-upgrade has possibly worked.
I repeated the dkms package installation after uninstall.
Suggestion on Kali site is this which i used:
apt update
apt install realtek-rtl88xxau-dkms

I've had no problems installing the dkms package today after an "apt update && apt upgrade". It installed without a hitch. Maybe run another update and try again.
Don't get too excited if you get it installed, because the driver doesn't seem to be compatible with the latest kernel versions.

You can check out this post for a solution.
Hope that helps and please let us know how you go
